Have you ever accidentally left your LED flash turned on during the day and noticed your battery was almost dead by the time you got to it? If so, then trust me; you’re not alone. I’ve done it a few times myself while working on my car when some areas of the engine compartment were too dark for me to see.
But now, you can use a new free jailbreak tweak called FlashBar by iOS developer Cole Cabral to prevent that from happening ever again. The tweak displays an icon in the Status Bar whenever your LED flash is turned on.
